CAST: Recent results & future outlook
Papaevangelou, Thomas H.; Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Yıldız, Süleyman Cenk; Borghi, Silvia; Brauninger, Heinrich W.; Cantatore, G.; Çetin, Serkant Ali; Ezer, Cemile; Yıldız, Süleyman Cenk (Verlag Deutsches Elektronen-Synchrotron, 2010-07)The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipes of an LHC dipole. The analysis of data taken so far has shown no signal above the ... -
Low background x-ray detection with micromegas for axion research
Andriamonje, Samuel; Castel, J.F.; Dafni, Theopisti; Davenport, M.; Fanourakis, George; Ferrer-Ribas, Esther; Yıldız, Süleyman Cenk (IOP Publishing, 2014-01)Axion helioscopes aim at the detection of solar axions through their conversion into x-rays in laboratory magnetic fields. The use of low background x-ray detectors is an essential component contributing to the sensitivity ... -
New micromegas for axion searches in CAST
CAST Collaboration; Yıldız, Süleyman Cenk (Elsevier, 2011)Micromegas detectors have been taking data in the CAST experiment since 2002, occupying one opening (out of the two looking for sunrise axions) of the magnet and showing good performance and stability. Currently, three of ... -
The new micromegas X-ray detectors in CAST
Tomas, Antonio; Aune, Stephan; Dafni, Theopisti; Fanourakis, George K.; Ferrer-Ribas, Esther; Yıldız, Süleyman Cenk (John Wiley&Sons, 2011-07)The last generation of micromegas, called microbulk, are ahead of classical gas detectors (or even other kind of micro-pattern gas detectors) in gain stability, efficiency (by operation at high pressure), simplicity, ... -
Probing the eV-mass range for solar axions with CAST
Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Brauninger, Heinrich W.; Cantatore, G.; Carmona, J. M.; Çetin, Serkant Ali; Yıldız, Süleyman Cenk; CAST Collaboration (IEEE, 2010)The CERN Axion Solar Telescope (CAST) is searching for solar axions which could be produced in the core of the Sun via the so-called Primakoff effect. Not only would these hypothetical particles solve the strong CP problem, ... -
Rare event searches based on micromegas detectors: The T-REX project
Dafni, Theopisti; Aune, Stephan; Fanourakis, George K.; Ferrer-Ribas, Esther; Galan, J.; Garcia, J.A.; Yıldız, Süleyman Cenk (IOP Publishing, 2012)Micromegas readouts are an attractive option for many of the rare event searches, due to their performance regarding energy resolution, gain stability, homogeneity and material budget. The T-REX project aims at developing ... -
Ultralow background periods in CAST Micromegas detectors and tests in the Canfranc underground laboratory
Iguaz, F. J.; Dafni, Theopisti; Ferrer-Ribas, Esther; Galan, Javier; García, Ana I. M.; Gardikiotis, Antonios; Yıldız, Süleyman Cenk (IOP Publishing, 2011)Micromegas detectors have shown a low and stable background level in the CAST experiment due to their low radioactive materials, good energy resolution and spatial resolution. Since 2008, four ultralow background periods ... -
X-ray detection with Micromegas with background levels below 10-6keV-1cm-2s-1
Aune, Stephan; Aznar, Francisco; Calvet, David; Dafni, Theopisti; Diago, A.; Druillole, Frederic; Yıldız, Süleyman Cenk (IOP Publishing, 2013-12)Micromegas detectors are an optimum technological choice for the detection of low energy x-rays. The low background techniques applied to these detectors yielded remarkable background reductions over the years, being the ... -
X-ray detectors of the CAST experiment
Yıldız, Süleyman Cenk (IOP Publishing, 2014-03)CERN Axion Solar Telescope (CAST) is an experiment probing hypothetical particles: the axions, created in the solar core. Inside the transverse magnetic field of the CAST magnet, axions can be converted into x-rays, and ...
